Abstract. The fluctuation theorem for currents in semi-Markov processes
satisfying the condition of direction­time independence is proved. The
thermodynamic affinities as well as the corresponding fluctuating currents are
defined using graph theory and the cyclic representation of the process. The
fluctuation theorem is obtained by demonstrating a fundamental symmetry
property for the evolution operator of the process. This fundamental symmetry
